Abstract: In the case of an oil pump, which comprises a feed pump, a series of valves, an output line and a burner nozzle connected to the latter, there is a displacement piston connected to the output line, preferably close to the burner nozzle, which piston is displaced in a cylinder when the oil pump is switched off and consequently creates an inner space in which the oil is sucked out of the output line and the burner nozzle. When operation is commenced, the piston moves back again and forces the oil out of the inner space into the output line, so that the latter is then already filled with oil when pressure is applied, so that a steeper pressure increase occurs at the burner nozzle than was possible previously in the case of oil burners with oil scavenging. <IMAGE>

Abstract: An ion beam arrangement accepts a steady beam of ions from an ion source and forms a stream of ion bunches from it, so that the bunches or packets of ions can be subsequently utilised. The ion beam buncher consists of an electrode (2) to which a high frequency alternating potential (14) is applied to impart a velocity modulation to ions within the steady beam. This electrode is followed by a drift space (3) in which the velocity modulation results in the formation of the discrete bunches of ions, but without any overall increase in ion energy. These ion bunches can then be accelerated to high energy levels using a multistage alternating voltage linear accelerator (24, 25).

Abstract: 2.1 The invention is based on the object of executing the transformation in the shortest possible time and keeping the technical complexity comparatively low. 2.2 The object is achieved by the fact that the input values (Y1,1 to Y8,8) to be transformed are unidimensionally processed in two successive transformers (TR1, TR2). Between the two transformers, there is a block buffer store (BZS) having two buffer stores (ZS1, ZS2) which alternately store the subtotals (X1,1 to X8,8) formed in the first transformer, line-oriented and block by block. In the transformers (TR1, TR2), a multiplication of in each case eight input data of the blocks comprising eight by eight input data takes place, factors being used which are obtained from a particular transformation matrix (A). Following the multiplication, a pair-by-pair addition takes place until in each case only one subtotal (X'1,1) or an overall total (X1,1) is available which is rounded to n bits. 2.3 A preferred application of the invention is the recovery of magnetically stored spectral values. 3 The stages needed for carrying out the method are shown in a block diagram. <IMAGE>

Abstract: In order to press a viscous mass out of a cylindrical cartridge (10), a cartridge piston is used which has an integral piston body (14) with a sleeve (15) running parallel to the cartridge wall (11). If the plastic mass contained in the cartridge (10) inclines towards bonding the cartridge piston in place, there is the risk that the piston will be moved into an oblique position when being pressed forward. In order to stiffen the piston, a reinforcement ring (25) is inserted in a clamping fashion into the sleeve (15). The stiffness of the reinforcement ring (25) is greater than that of the piston body (14). The reinforcing body stiffens the piston against compression. Although the piston is, as a whole, rigid, the ability of the sleeve (15) to fit tightly against the cartridge wall (11) is preserved. <IMAGE>

Abstract: An electronic frequency inverter circuit receives input electrical power at a lower frequency and energizes in a range of higher frequencies a load circuit (36)(37) including gaseous discharge lamps which varies with frequency. First and second switches (30)(31) are operated alternately by a logic circuit mode control (40) such that the switches operate at the high frequency range and the frequency of current in the load circuit varies as the magnitude of said source voltage (10) varies. The load circuit has an impedance such that the peak amplitude of the load current remains substantially constant despite variations in the magnitude of said source voltage to achieve a desirable crest factor for the load current. A high current limit circuit rapidly turns off the switches when excessively high current begins to flow through the switches. Low voltage is supplied in port from the high frequency current. Normal operation is ensured during start-up, for reduced line voltage and for a semiconductor chip embodiment.
